I know all about alpha channels – I know to set it to Quicktime + Alpha – I know which file formats can handle alpha channels – I teach FCP, Photoshop, and 3dsMax classes – and if i didn’t know all about these things, I wouldn’t be able to use numerous other programs for 5 years and never have a problem – which is what i said in my post – so if you’d read my post and acutally think about it, you wouldn’t post stupid crap like “set it to Quicktime + Alpha” – all the settings are correct – the piece of crap doesn’t work. And if you knew what you were talking about you also wouldn’t post “it works on my computer”. I have no doubt that it works on your computer, my point is that it doesn’t work on mine. you’re a moron if you think that the fact it works on yours proves that it works on mine. buggy software doesn’t always produce errors that are replicatable on other computers, buggy software produces random errors that occur at random and for no good reason. Now excuse me, I have to go figure out why Motion doesn’t update my Photoshop files, and Reconnect media isn’t easy to find (ie option click on file, or in Menus).
